COTTON-GIN BRUSH.

Specification of Letters Patent.

Application filed February 16, 1911.

Serial No. 608,898.

T 0 all whom it may concern:

Be it known that I, SMITH F. KRUPP, a citizen of the United States, anda resident of Memphis, in the county of Shelby and State of Tennessee,have invented a new and Improved Cotton-Gin Brush, of which thefollowing is a full, clear, and exact description.

My invention relates to brushes, and particularly to brushes which incotton gins are brought into contact with the periphery of the sawcylinder for removing lint cotton therefrom, and discharging it from themachine.

The object of the invention is to provide a durable rotary brushconstructed of interchangeable parts which will readily permit ofrepairs being made, the brush being so constructed that it will preserveits running balance.

In the drawings similar characters of reference indicate correspondingparts in all the views, in which Figure 1 is a sectional view on theline 11 of Fig. 2; Fig. 2 is a sectional view on the line 2-2 of Fig. 1;Fig. 3 is a fragmentary view of the U-shaped member, showing the bent-upflange which rests against the head of the screw and serves as a locktherefor, and Fig. 4 is a fragmentary view in perspective, showing howthe flanges on the U-shaped members engage the shoulders on the ribs.

By referring to the drawings it will be seen that head members 6 arekeyed to the shaft 5, these head members 6 having annular flanges 7there being threaded orifices 8 spaced apart in the said flanges. Theheads 6 are spaced from each other and disposed across from one head tothe other, and resting on the flanges there is a plurality of ribs 9,the said ribs being spaced from each other. Secured to the ribs 9 arebrush members 10. As best shown in Fig. 4 of the drawings, the ribs 9are constructed with shoulders 11. Disposed between the ribs 9respectively, and extending across from one of the heads 6 t0 the other,there are U-shaped members 12, having outwardly extending flanges 13,the flanges 13 being disposed against the shoulders 11 on theneighboring ribs 9. Screw members 14, with square heads 15, are disposedin the orifices 16 in the U-shaped members 12, the said screws 14meshing in the threaded orifices 8 in the flanges 7 on the heads 6.

The sides of the U-shaped members 12 are punched to form bent-upportions 17 which engage the square heads 15 of the screw members 14,and serve as locks therefor. One or more rings 18 are provided withthreaded orifices 19, in which screws 20 mesh, the said. screws 20 beingdisposed through openings 21 in the U-shaped members 12, and beinglocked in position by the bent-up portions 17 on the ribs 12.

The rotary brush which is described in this specification may bemanufactured at very little expense, and as the parts areinterchangeable, and may be readily replaced, it will be seen thatrepairs may be quickly made at very little expense.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. In a cotton gin brush, two head members spaced apart, ribs forholding brush members spaced apart and extending from one head member tothe other, members U- shaped in cross section spaced from each other anddisposed between the ribs, the U- shaped members having flanges forengaging neighboring ribs, and means for detachably securing theU-shaped members to the head members.

2. In a cotton gin brush, a head member, ribs for holding brushes spacedapart around the head member, members U-shaped in cross section spacedfrom each other. and

disposed between theribs, the U-shaped members having flanges whichengage neighboring ribs, and means for detachably securing the U-shapedmembers to the head member.

8. In a cotton gin brush a head member having orifices spaced apart,ribs for holding brush members, spaced apart around the head member,members disposed between the ribs respectively, and having orifices,flanges for engaging neighboring ribs, and additional flanges and screwmembers disposed in the orifices for holding the second-mentionedmembers relatively to the head member, the screw members being engagedby the said additional flanges to prevent their being turned.

4. In a cotton gin brush two head members spaced apart, ribs for holdingbrush members spaced apart and extending from one head member to theother, members disposed between the ribs respectively having bent-upportions, orifices, flanges for engaging neighboring ribs, and screwmembers disposed in the orifices for holding the second-mentionedmembers relatively to the head members, the screw members being engagedby the bent-up portions to prevent their being turned.

5. In a cotton gin brush a shaft, two head members having threadedorifices, spaced from each other and keyed to the shaft, ribs spacedfrom each other and extending from one head member to the other,U-shaped members disposed between the ribs having flanges engagingneighboring ribs and orifices in alinement with the threaded orifices inthe head members respectively, screw members disposed through theorifices in the U-shaped members and meshing in the threaded orifices inthe head members, a ring member disposed between the head members, andmeans for securing the Ushaped members to the ring member. In testimonywhereof I have signed my name to this specification in the presence oftwo subscribing witnesses.
